Abstract

Budidaya ikan air tawar memiliki peran penting dalam menjaga ketahanan pangan dan meningkatkan perekonomian, namun metode konvensional sering kali kurang tepat dalam pemberian pakan dan pengelolaan kualitas air. Untuk mengatasi permasalahan tersebut, dirancang sistem kontrol dan monitoring cerdas berbasis mikrokontroler ESP32 yang memantau suhu, pH, TDS, dan ketinggian air menggunakan sensor DS18B20, pH-4502C, TDS Meter, dan HC-SR04. Hasil pengujian menunjukkan tingkat kesalahan terkecil pada sensor TDS (1,18 %), diikuti oleh pH-4502C (2,46 %), HC-SR04 (2,48 %), dan DS18B20 (3,28 %). Sistem ini mengaktifkan pompa aerator dan filter secara otomatis melalui timer DH48S-S, di mana sensor TDS akan menyalakan pompa filter ketika nilai TDS ≥ 500 ppm. Solenoid input beroperasi ketika ketinggian air ≤ 40 cm dan berhenti pada ketinggian ≥ 90 cm, sedangkan solenoid output diatur melalui penjadwalan timer THC15A. Heater aktif pada suhu ≤ 20 °C dan nonaktif pada suhu ≥ 28 °C. Auto feeder bekerja berdasarkan timer THC15A, dengan jumlah pakan diatur menggunakan timer H3Y-2. Pemantauan jarak jauh serta notifikasi otomatis dilakukan melalui Telegram. Dengan demikian, sistem yang dikembangkan terbukti efisien, adaptif, dan aplikatif untuk mendukung budidaya ikan air tawar secara berkelanjutan.

Abstract

This study aims to determine the strategies used by students to improve their basic technical skills in Bulu Tangkis at Universitas Negeri Medan. This research employed a qualitative approach with a field research design. The subjects of this study were students who actively participated in badminton activities on campus. Data collection techniques included observation, interviews, and documentation. The data were analyzed through data reduction, data display, and conclusion drawing. The results showed that students applied several strategies to improve their basic badminton techniques, including regular practice individually or with peers, utilizing digital media to learn game techniques, participating in campus sports activities, and evaluating their playing performance. In addition, motivation, social support, and the availability of sports facilities also played an important role in improving students' basic badminton skills. Therefore, consistent training strategies and a supportive environment can help students improve their badminton playing skills effectively. Keywords: training strategies, basic techniques, badminton, students.
